In the race to make food production and consumption more sustainable, South Asia is key.
Home to one quarter of humanity — one-fifth of whom are youth — the region has the world’s largest concentration of poverty and malnutrition. While South Asia produces one quarter of the world’s consumed food, its agrifood systems today face formidable poverty reduction, climate change adaptation and mitigation, environmental health, and biodiversity challenges. Significant hurdles remain to secure an adequate and affordable supply of diverse foods necessary for sustainable and healthy diets.
South Asia’s predominantly rice-based farming systems are crucial to food security and political and economic stability, but parts of this region are threatened by unsustainable groundwater withdrawal — the region extracts one-quarter of global groundwater — due to food and energy policy distortions. South Asia’s farmers are both contributors to and victims of climate change and extreme weather that disproportionately affect resource-poor and women farmers.
The region needs food systems that generate profits and incentivize farmers to produce nutritious foods, while also reducing prices for consumers purchasing healthy products by shortening and reducing inefficiencies within value chains. A new CGIAR Research Initiative, Transforming Agrifood Systems in South Asia (TAFSSA), aims to address challenges.
Punjab Chief Minister Bhagwant Mann met with experts from the International Maize and Wheat Improvement Center (CIMMYT) to promote crop diversification and use of Direct Sowing Rice (DSR) Basmati as part of the Borlaug Institute for South Asia (BISA) project.
In a meeting with CIMMYT Director General Bram Govaerts, water shortages were an integral part of the discussion. Mann encouraged use of BISA models across the state that require less water consumption than other methods, without impacting farmers’ income.
Mann also highlighted the potential of crops like maize, pulses, oilseeds, vegetables, bamboo, popular, and fruit such as guava and kinoo.

The eastern Indo-Gangetic plains (EIGP) have a higher density of rural poverty and food insecurity than any other region. The region’s intensive rice-wheat cropping system has large yield gaps, which are far higher than anywhere in South Asia, coupled with an increasing environmental footprint due to conventional agricultural practices.
To sustainably enhance cereal crop productivity and improve smallholder farmers’ livelihoods in Bangladesh, India, and Nepal, the Cereal Systems Initiative for South Asia (CSISA), a science-driven and impacts-oriented regional project led by the International Maize and Wheat Improvement Center (CIMMYT), was launched in 2009.
Over the years, working with public and private partners, CSISA has helped smallholder farmers increase their yield and supported widespread adoption of resource-conserving and climate-resilient farming technologies and practices. Through three phases from 2009 to 2021, the project impacted nearly 8.5 million farmers (mainly smallholders) through its research and agri-system innovation interventions.
A new three-and-a-half-year commitment in India by the Bill & Melinda Gates Foundation reinforces the project’s importance and value in reducing food insecurity and improving overall agri-food systems in the region.
“CSISA, over more than a decade, has built up a strong multi-institutional, interactive, and participatory team at all levels in the region,” said Peter Craufurd, project leader of CSISA in India. “It has developed competencies and skills that include problem-solving agronomy research, cross-cutting tools and analytics, policy reform, and capacity development to strengthen cropping systems for smallholder farmers in the region.”

The overarching objective of CSISA 4.0 is to transform how agronomic research and extension are implemented and embedded in decision-making and policy processes, primarily in India, where CSISA has the most experience and influence. Phase 4.0 will leverage the investments made in India in the third phase and focus on institutionalizing interventions through partnerships with the national and state agricultural systems, including on-ground strategic partnerships with civil society and the private sectors. According to Craufurd, Phase 4.0 will further strengthen the pathways established and scale the impact, particularly the institutional research and development capacity and strategic partnerships thus far established in India, through its seven focussed work areas, including gender empowerment.
“We are confident of our strong partnership with the national systems led by the Indian Council of Agricultural Research (ICAR) to support Indian farmers with improved yield and productivity,” said R.K. Malik, CSISA India coordinator. “Over the last decade, CSISA has built a strong track record for agronomy at scale that can help transform agri-research delivery systems in the region. There is also the opportunity to make CSISA outputs and products portable or useable for other stakeholders addressing food insecurity in the region in the future.”
Implemented jointly with CGIAR partners the International Rice Research Institute (IRRI) and the International Food Policy Research Institute (IFPRI), the initiative has been a successful regional approach to impactful agronomy programming. The CSISA team hopes to continue supporting the smallholder farmers in the region to optimize yield and contribute to the region’s food security.
Securing the Food Systems of Asian Mega-Deltas (AMD) for Climate and Livelihood Resilience aims to create resilient, inclusive and productive deltas — which maintain socio-ecological integrity, adapt to climatic and other stressors, and support human prosperity and wellbeing — by removing systemic barriers to the scaling of transformative technologies and practices at community, national and regional levels.
This objective will be achieved through:
Adapting deltaic production systems by identifying, synthesizing, evaluating, adapting and scaling interventions to ensure systems can adapt to and mitigate the effects of salinity, flooding, drought, terminal heat and sinking land.
Nutrition-sensitive deltaic agrifood systems, developed through the promotion of sustainable production and consumption of nutritious foods in Asian mega-deltas, by involving institutional stakeholders in the co-production of nutrition-sensitive interventions.
De-risking delta-oriented value chains by assessing the potential of digital climate advisory and complementing services to address climate risks among vulnerable groups, supporting development of improved and inclusive digital and bundled services, and identifying and developing financing models and partnerships to achieve scale.
Joined-up, gender equitable, inclusive deltaic systems governance, informed by transdisciplinary research evidence, local knowledge and political economy insights used to coordinate multi-stakeholder dialogues for more coherent water-agriculture-environment policies and strategies; collaborative, networked implementation practices; and gender-equitable and socially inclusive governance innovations.
Evidence-based delta development planning at the macro-level to ensure plans/policies incorporate inclusive and climate-proof approaches to food systems transformation.
Working across South Asia, the Transforming Agrifood Systems in South Asia (TAFSSA) Initiative will deliver a coordinated program of research and engagement across the food production to consumption continuum to improve equitable access to sustainable healthy diets, improve farmer livelihoods and resilience, and conserve land, air, and groundwater resources.
TAFSSA aims to propel evidence into impact through engagement with public and private partners across the production-to-consumption continuum, to achieve productive, environmentally-sound South Asian agrifood systems that support equitable access to sustainable healthy diets.
This objective will be achieved through:
Facilitating agrifood systems transformation through inclusive learning platforms, public data systems and partnerships: building new and enhancing existing learning platforms; improving the evidence base; increasing quality data availability and accessibility; and demonstrating the value of integrated agrifood systems datasets.
Transforming agroecosystems and rural economies to boost income, generate jobs and support diversified food production within environmental boundaries: generating linkages between farmers, landscapes and markets to diversify agricultural production, increase farmers’ incomes and foster rural entrepreneurship within environmental boundaries.
Improving access to and affordability of sustainably produced healthy foods through evidence and actions across the food system: creating favorable environments for diversification; improving access to inputs for and marketability of sustainable nutritious food; and improving access to healthy food for the poor through changes in food retail environments.
Understanding behavioral and structural determinants of sustainable healthy diets: studying dietary practices of food consumers; identifying determinants of food choices; and testing innovations to support consumption of sustainable healthy diets.
Building resilience and mitigating environmental impact: examining how South Asia can produce healthy diets within an environmentally safe and socially equitable operating space, and in consideration of ongoing climate change and farmers’ resilience to shocks.
Sagar has been working at CIMMYT-Nepal since December 2015, contributing to various projects. His main focus has been on the CSISA initiative, which aims to research and scale up resource-saving technologies within Nepal’s cereal systems. Through his work, he has developed expertise in technology scaling within cereal systems, developing market systems, and strengthening governance in the agricultural research and extension services sector. This is in part due to his strong understanding of local contextual factors that influence the adoption of sustainable intensification technologies, including mechanization.
Since 2024, Sagar has turned his attention to generating innovations, tools and scaling pathways in the mixed farming systems of the mid-hills of Nepal as part of the CGIAR Mixed Farming Systems (MFS) Initiative.

It’s a familiar problem in international agricultural development – a project with external funding and support has achieved impressive early results, but the money is running out, the time is growing short, and there’s not a clear plan in place to continue and extend the program’s success.
Over the past seven years, the German development agency Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) established Green Innovation Centers in 13 countries in Africa and two in Asia, partnering with the International Maize and Wheat Improvement Center (CIMMYT) to support projects that introduce mechanization in a way that improves long-term food security and prompts economic growth. Now, as the project enters its final two years of funding, GIZ and CIMMYT are focused on ensuring the gains produced by the Green Innovation Centers are not lost.
Like any complex challenge, there’s not just one solution to the sustainability problem – but CIMMYT is working to address a massive question around why pilots fail in agricultural development by implementing a systematic approach to scalability that recognizes the critical importance of context and puts projects on a sustainable path before the money is gone.
Training the trainers
As the Green Innovation Centers enter a crucial, final stage, a CIMMYT-led team recently completed training for seven GIZ staff from Ivory Coast, Togo, Ethiopia, and Zambia, who are now certified to facilitate CIMMYT’s Scaling Scan tool and train others to put agricultural innovations in their home countries on a solid path for growth. The training team included CIMMYT scaling advisor Lennart Woltering, CIMMYT mechanization support specialist Leon Jamann, and students from Germany’s University of Hohenheim and Weihenstephan-Triesdorf University.
The Scaling Scan is a practical tool that helps users set a defined growth ambition, analyze their readiness to scale using ten core ingredients, and identify specific areas that need attention in order to reach the scaling ambition.
The GIZ staff learned to use the Scaling Scan by applying it to early stage innovations in their home countries, ranging from commercial fodder production in the Southern Province of Zambia to seed value chains in the Oromia and Amhara regions of Ethiopia.

What will scale up in Ethiopia?
In Ethiopia, smallholding farmers producing legumes, wheat and maize struggle to increase their yield to a level that can improve food security, generate higher incomes for producers and their families, and promote economic growth and jobs in agricultural communities. To help smallholders develop sustainable solutions, GIZ senior advisor Molla Dessalegn worked with his Green Innovation Center team to brainstorm and launch a range of 20 proposed innovations – from risk mitigation and new contract structures to introduction of new technology – all with the aim of improving agricultural yields.
To date, these innovations have introduced over 200,000 Ethiopian smallholders to new knowledge and practices to improve their output. But with the project exit bearing down, Molla and his team were eager to identify which innovations held the most promise for survival and growth beyond the endpoint. So they put their pilot projects to the test using the Scaling Scan.
The scan involves an intensive, day-long seminar originally designed for in-person delivery, but remote versions have also proved successful as COVID limited global travel. The scan focuses on thorough analysis and scoring of the current state of a pilot project and its potential for growth given the realities of conditions on the ground.
Facilitators lead project managers through evaluation of the ten ingredients required for successful scaling, from finance and collaboration to technology, know-how, and public sector governance. The outcome is a clear data set assessing the scalability of the pilot and directing attention to specific areas where improvement is needed before a project can expect serious growth.
An unexpected outcome
What emerged from the scan surprised Molla. Some of the strategies he saw as most successful in the early stages, such as a contract farming program, scored poorly, whereas the scan identified deployment of mobile seed cleaners as a solution that held particular promise for scalability. These outcomes prompted the team to refocus efforts on this strategy.
About 95 percent of Ethiopian smallholders rely on informal seed systems, either saving and reusing seed or exchanging low quality seed with other farmers. Seed cleaning plays a critical role in helping farmers build a high quality, high yield seed development system. Molla and his team had already worked with smallholder cooperatives in Oromia to distribute three mobile seed cleaners, and they knew these machines were being heavily relied upon by farmers in this region.
The Scaling Scan showed them, among other things, that the successful adoption of the seed cleaners had even more potential – it was an innovation that could be sustained and even expanded by local stakeholders, including the Ministry of Agriculture.
This result prompted Molla to recommend investment in additional mobile seed cleaners – four to serve cooperatives in the Amhara region and a fifth for the West Arsi district in Oromia. These machines are now in operation and helping additional smallholders improve the quality of their seed stock. This initial expansion confirms the Scaling Scan results – and CIMMYT plans to continue supporting this growth with the purchase of another round of seed cleaners.
The Scaling Scan also identified problems with the business model for sustaining the mobile seed cleaners through cooperatives in Ethiopia, and this outcome directed the Green Innovation Centers to partner with a consultant to develop improvements in this area. In this way, one of the most important values of the scan is its ability to guide decision-making.
Scaling up the future
Seed cleaners alone won’t solve every yield problem for Ethiopian farmers, but the scan has now guided the initial implementation – and contextual adaptation – of a new form of agricultural mechanization across two regions of the country, with the promise of more to come.
And there’s more to come from the Scaling Scan as well.
Now that he’s received certification as a trainer, Molla plans to help farmers, officials, and other development workers adopt this rigorous approach to evaluating innovations that show potential. When funding for his project ends in 2024, he will be leaving 300,000 smallholders in Ethiopia with more than machines – he will be leaving them with the knowledge, experience, and practices to make the most of the technological solutions that are improving their yields today and building a more secure future for their communities.
“I am happy with this wheat variety and all the support from the project,” said Agere Worku, a female farmer in Ethiopia working with the International Maize and Wheat Improvement Center (CIMMYT). “It is a lot of money that I will earn as a female farmer in my life.”
Participants were given Kingbird seeds, a new wheat variety, to plant in their smallholdings. The project then supported them through capacity building and advice on smart soil, water management, plant protection and agronomic packages.
“We prepared six hectares of land and sowed 1.1 tons of Kingbird seed,” said Yeshiwas Worku, chair of the Melke Yegna Tefsa Association. “There were other wheat varieties, such as Danda’a, adjacent to our experimental plot and the difference in yields was very visible. The other members of the association were eager to get Kingbird seeds, which are very different in terms of quality, yields, maturity, and disease tolerance.”
“CIMMYT is a life changer for me,” said Buzayehu Getahun, a farmer in Jeju, in the Oromia region. “I produced 3.7 tons on 0.75 hectares. Interestingly, I earned around 132,000 Ethiopian Birr (US$2,500) from this yield. I plan to build a new house for my mother in my village and will be blessed by her at her old age,” said Getahun.

The impact on female farmers
After involvement in the pilot, the female farmers produced higher yields than they had experienced before.
“I used to harvest wheat three times in the previous years and earned only 0.66 tons of wheat per 0.75 hectare using seeds of other wheat varieties,” explained Worku. “But now thanks to support from CIMMYT, the yield has increased four times than the previous years; I produced 2.4 tons per 0.75 hectares. I am very happy with the high yield and feel encouraged to reinvest in other agricultural activities.”
A second female farmer, Melishew Tedela, said, “I am happy with this seed and all the support from the project. I can be witness that the other farmers who didn’t get this variety were not happy with their low yields of wheat.”

The future of lowland wheat farming
Bekele Geleta Abeyo, wheat breeder and Ethiopia Country Representative at CIMMYT, said, “The Government of Ethiopia is emphasizing increasing irrigated wheat production and productivity in the lowlands to complement the intensification of rainfed wheat production in the highlands in order to achieve self-sufficiency by 2023 and feed the ever-growing population.”
With world wheat prices skyrocketing due to the Ukraine conflict, wheat technology generation and dissemination are key for sustainable agricultural practices.
CIMMYT is working to replace obsolete wheat varieties in Ethiopia that are susceptible to wheat rust, particularly yellow and stem rust, with disease-resistant products. Newer varieties like Kingbird are rust-resistant and therefore produce higher yields.

As the Russia-Ukraine war continues to degrade global food security, the Australian who leads the global effort on improving wheat production has set out the concrete actions needed by governments and investors to mitigate the food crisis, stabilise supply and transition to greater agrifood system resilience.
Alison Bentley leads the Global Wheat Program at the International Maize and Wheat Improvement Center (CIMMYT), the renowned research organisation from which more than 90 per cent of the wheat varieties grown in Australia can be traced. She will be addressing the Crawford Fund’s international conference Celebrating Agriculture for Development – Outcomes, Impacts and the Way Ahead this week in Parliament House, Canberra. The conference will also be addressed by the Minister for Agriculture, Fisheries and Forestry, Senator The Hon, Murray Watt.
“The broad food security impacts of the Russia-Ukraine war highlight the fragility of the global food supply, but the war is only one of a multitude of problems that we’ll be facing for many years to come. Few will remain unaffected,” said Alison Bentley, who was the lead author in a recently published related article in Nature Food.
“More than 2.5 billion people worldwide consume wheat-based foods. We need to move beyond defining the problem to implementing practical actions to ensure stable food supply, safeguard the livelihoods of millions of vulnerable people and bring resilience to our global agrifood system, and we will all benefit,” she said.
“The first priority is to mitigate the immediate crisis by boosting wheat production by bundling existing agronomic and breeding improvements and sustainable farming practices, just as Australia and other wealthy countries are doing. This will reduce dependence on imported grain and fertilizer in poorer countries.”
“We have learned since the Green Revolution that this must be done within agro-ecological boundaries, with high-yielding disease-resistant wheat and by mainstreaming capacity for pest and disease monitoring. Importantly, we also need to address climate change, gender disparities, nutrition insufficiency and increase investment in agricultural research,” she concluded.
The Fund’s annual conference will bring together international and Australian specialists to look at the mutual benefit and impacts of investment in global food security and poverty alleviation, and consider the effects of emerging threats including climate change and changing geo-political conditions on agricultural production, food chains and the environment.
Other speakers include international affairs specialist Allan Gyngell, climate change and security specialist Robert Glasser and renowned international economist Phil Pardey.

Him Lal Neupane has been in the business of agriculture for more than a decade. His company Annupurna Suppliers, in Banke District, Nepal, trades in agri products and has an annual turnover of around $626,000, up from $195,000 eight years ago.
Recently, Neupane has been heavily investing in maize. He says involvement from the International Maize and Wheat Improvement Center (CIMMYT) in market strengthening has given him the confidence to go big on the crop. He encountered CIMMYT through the meetings led by the organization in the district, as part of its Nepal Seed and Fertilizer (NSAF) project. In the meetings, he was able to hear perspectives on maize production from leading market experts, as well as government officials. Getting direct access to high level government representatives and agricultural scientists was incredibly fruitful and raised his confidence to invest in maize. He also got to air his own grievances about the industry and learn more from other farmers.
“I learnt that the project was invested in training farmers to produce better quality maize,” said Neupane. “If we get quality products from farmers, I immediately deduced that there is a great chance that the product will keep doing well in the market.”

In 2022, Neupane bought a truck and has been constructing a massive storage facility that can store up to 4 million kilograms of produce. He has plans for proper grading and drying of maize in the facility to sell to industrial buyers.
The majority maize in Nepal is used as feed for the poultry industry, so there is high value for the crop in the market. “Since Nepal is a big consumer of poultry products and will remain so, it is inevitable that locally produced maize will sell,” explained Neupane.
Neupane went into agriculture because he could not secure employment after completing higher education. He grew up learning and practicing farming, so he understood farmers’ plights and wanted to start a company that would improve their lives. He also wants to grow the industry to curb the country’s maize import dependence, which has been affected by recent disruptions like the Ukraine conflict and the pandemic. Annually, Nepal imports around $120 million worth of maize, which depletes the country’s foreign currency reserves.
CIMMYT’s efforts in developing the maize market through value chain coordination and private public partnerships intend to help stakeholders at every level of the industry, from farmers to suppliers like Neupane, whose company’s growth represents a strong reinforcement of confidence in domestic maize production.

After four decades, new site-specific fertilizer recommendations for rice have been introduced in Nepal that will help farmers increase the crop’s productivity by 10-30%, compared to their current practices.
The Ministry of Agriculture and Livestock Development (MoALD) endorsed the new fertilizer recommendations for rice crop at a consultative workshop in July 2022 held in Kathmandu. Developed by the International Maize and Wheat Improvement Center (CIMMYT), in close collaboration with the Nepal Agriculture Research Council’s (NARC) National Soil Science Research Center (NSSRC) and International Fertilizer Development Center (IFDC), the new regime replaces the existing blanket approach of recommendations to help increase crop yields and fertilizer use efficiency.
The blanket approach assumed the whole country as one domain despite the heterogeneity in soils, other biophysical conditions and agronomic management practices, including crop varieties. As a result, fertilizers were under-utilized in low fertile soils or overused in farms with high soil fertility status, thereby farmers were not able to obtain the achievable yield.
Unlike the generic recommendations, the site-specific fertilizer management will help farmers to determine the crop’s fertilizer requirements based on soil fertility status of a particular farm, attainable yield target of the selected crop variety, crop’s yield response to fertilizers and agronomic management practices, such as irrigation, cropping systems etc. In other words, this new regime allows farmers to produce more with less fertilizers through a balanced application of fertilizers based on available soil properties.
Old is not always gold
Generally, soil fertility status changes every 3-5 years when there is continuous nutrient removal from soils due to an intensive cropping system with the adoption of high nutrient demanding improved and hybrid varieties. Thus, soil fertility management recommendations should be updated periodically but the existing recommendations were not updated since 1976.
Realizing the limitations, CIMMYT through the Nepal Seed and Fertilizer (NSAF) project, supported by USAID, worked with NSSRC and IFDC to formulate fertilizer recommendations for major cereal crops and vegetables for specific domains of the country.
Under NSSRC’s leadership, a ‘Fertilizer Recommendation Committee’ comprising of a dedicated team of soil scientists within NSSRC and NSAF experts was formed to develop site-specific fertilizer recommendations using the Soil-SMART framework for delivering balanced fertilizers to farmers. Based on soil fertility status, agro-climate, irrigation regimes and geography, the country was divided into six soil fertility domains — four in the Terai region (Eastern, Central, Western and Far-western), one in inner Terai and one in the hills. Under each domain, recommendations were based on the attainable yield, crop variety, and irrigation regime.
This approach was first tested for rice crop.
Formulating new recommendations for rice
Three fundamental steps were used to develop site-specific fertilizer recommendations, which included: i) selection of yield goal, ii) estimation of crop nutrient requirement, and iii) estimation of indigenous nutrient supplies. To collect this information, NSAF and the committee designed field trials on nutrient omission and nutrient rates to determine the yield limiting nutrients and their optimum rate, respectively. Data from fertilizer trials conducted by different research institutes and universities, including trials from the project sites were collected and analyzed by the team to see the crop’s yield response to fertilizers. A modeling approach called Quantitative Evaluation of fertility of the tropical soils (QUEFTS) was also used to estimate the indigenous nutrient supply and attainable yield target of rice for different soil fertility domains. This model was applied as an alternate to extrapolate recommendations in areas where field data were not available, considering large financial and human resources required otherwise to conduct numerous field trials across different soil types and agro ecological zones. The model was validated with field trial data before making extrapolation of the recommendations. The QUEFTS model used soil properties from Nepal’s first digital soil map to identify nutrient status and deficiency.
In addition to agronomic optimum rate, an economic analysis was also conducted to see economic variability of the recommendations.
The newly developed recommendations provide guidance for balanced fertilization as it includes micronutrients zinc and boron, and organic inputs in addition to three major nutrients —Nitrogen, Potassium and Phosphorous (NPK). Results from field trials suggested that the new recommendation could increase rice productivity by 10-30% compared to existing farmers’ practice.

Advocating for endorsement
A three-day workshop was organized by CIMMYT and NSSRC to primarily share and approve the recommended fertilizer dose for rice crop as well as its relevance to achieve potential yield at farm level. Rajendra Mishra, joint secretary of MoALD inaugurated the event that was chaired by the Director of NARC’s Crop and Horticulture Research. Workshop attendees included MoALD, NARC, Department of Agriculture, USAID Nepal, secretaries from the Province Ministry of Land Management, soil scientists, university professors, agronomists and other high-level government officials.
During the workshop, NSAF explained the application of QUEFTS model with reference to the case of rice based on the field trial data for domain specific fertilizer recommendations. Shree Prasad Vista, soil scientist at NSSRC, summarized the results for rice as the approach and facilitated its approval from MoALD. The participants also discussed on strategies to link with the extension system to reach a large number of farmers through the three-tier governments. Fourteen research papers on nutrient management for major cereal crops were also reviewed at the event.
“I congratulate NARC for this historical work on updating the fertilizer recommendations after 46 years. Now, we are moving towards sustainable soil fertility management by adopting site-specific fertilizer recommendations,” said MoALD Secretary Govinda Prasad Sharma.
Although the recommendation for rice was a significant output of the workshop, fertilizer recommendations for other major crops will be carried out following a similar process.
NARC’s Executive Director Deepak Bhandari commented, “It is our pleasure to move from a blanket approach to site-specific approach. This is a milestone for agricultural research in the country and I would like to thank all the scientists, NSAF project and USAID’s support for this notable achievement.”
Similarly, speaking at the event, Jason Seuc, Director of Economic Growth Office at USAID Nepal, emphasized the importance of soil fertility management for achieving food security targets set by the Government of Nepal. Seuc remarked that a sustainable soil fertility management is critical not only for food security but also for reducing the environmental pollution.
“For several years, we’ve been building dense data sets with colleagues from the Indian Agricultural Research Council, which have allowed us to unravel complex farm realities through big data analytics, and to determine what agricultural management practices really matter in smallholder systems,” said Andrew McDonald ’94, M.S. ’98, Ph.D. ’03, associate professor of soil and crop sciences in the College of Agriculture and Life Sciences. “This process has confirmed that planting dates are the foundation for climate resilience and productivity outcomes in the dominant rice-wheat cropping systems in the eastern sector in India.”
The research was conducted through the Cereal Systems Initiative for South Asia (CSISA). CSISA, which is led by CIMMYT with the International Rice Research Institute and the International Food Policy Research Institute as research partners, was established in 2009 to promote durable change at scale in South Asia’s cereal-based cropping systems.
Researchers found that farmers in eastern India could increase yield by planting wheat earlier – avoiding heat stress as the crop matures – and quantified the potential gains in yields and farm revenues for the region. They also found that the intervention would not negatively impact rice productivity, a key consideration for farmers. Rice alternates with wheat on the cropping calendar, with many farmers growing rice in the wet season and wheat in the dry season.
The study also provides new recommendations for rice sowing dates and types of cultivars, to accommodate the earlier sowing of wheat.
“Farmers are not just managing single crops. They are managing a sequence of decisions,” said McDonald, who has a joint appointment in the Department of Global Development. “Taking a cropping systems approach and understanding how things cascade and interlink informs our research approach and is reflected in the recommendations that emerged from this analysis. Climate resilient wheat starts with rice.”
The research is the result of years of collaboration with international groups and government agencies in India, which have identified the Eastern Ganges Plain as the area with the most potential growth in production. The region will become essential, McDonald said, as the demand for wheat grows, and climate change makes production more difficult and unpredictable; just this year, record heat waves in March and April and food shortages caused by the war in Ukraine – both of which prompted India’s government to instate a ban on wheat exports – have highlighted the need for increased yields and more sustainable farming practices.
“In the bigger sense, this research is timely because the hazards of climate change aren’t just a hypothetical,” McDonald said. “Many of these areas are stress-prone environments, and extreme weather already constrains productivity. Identifying pragmatic strategies that help farmers navigate current extremes will establish a sound foundation for adapting to progressive climate change.”
Poverty is endemic in the Eastern Ganges Plain, and the region is dominated by small landholders, with varying practices and access to resources. The breadth and specificity of the data collected and analyzed in the study – including field and household survey data, satellite data, and dynamic crop simulations – allowed researchers to understand regional small farms’ challenges and the barriers to change.
“At the end of the day, none of this matters unless farmers opt in,” McDonald said. “There’s a spatial dimension and a household dimension to opportunity. If we can target approaches accordingly, then we hope to position farmers to make management changes that will benefit the entire food system.”
The study was co-authored with researchers from the Australian Department of Primary Industries and Regional Development, the International Rice Research Institute, the International Maize and Wheat Improvement Center, the International Food Policy Research Institute, the Indian Council of Agricultural Research and Bihar Agricultural University. The research was supported by the Bill and Melinda Gates Foundation and the U.S. Agency for International Development through grants to the Cereal Systems Initiative for South Asia, which is led by the International Maize and Wheat Improvement Center.

For thousands of years, farmers in Afghanistan, Turkey and other countries in the region, have been breeding wheat, working closely with the environment to develop traditional wheat varieties known as landraces. Untouched by scientific breeding, landraces were uniquely adapted to their environment and highly nutritious.
As agriculture became more modernised and intensified, it threatened to push these traditional landraces into extinction, resulting in the loss of valuable genetic diversity. Institutions around the world decided to act, forming germplasm collections known as genebanks to safely house these landraces.
In 2009, a team of wheat scientists from the International Maize and Wheat Improvement Center (CIMMYT), the International Center for Agricultural Research in the Dry Areas (ICARDA), the UN Food and Agriculture Organization (FAO), and national partners set off on a five-year expedition across Central Asia to collect as many landraces as they could find. The project, led by FAO Cereal Breeder and former CIMMYT Principal Scientist Alexey Morgunov, was made possible by the International Treaty on Plant Genetic Resources for Food and Agriculture Benefit-Sharing Fund.
The project had two main missions. The first is to preserve landrace cultivation in three countries, Afghanistan, Turkey and other countries in the region by selecting, purifying, and multiplying the landraces and giving them back to farmers. The second is to scientifically evaluate, characterize and use these landrace varieties in ongoing breeding programmes, exchange the information between the countries, and to deposit the seeds in genebanks to safely preserve them for future generations.
The latest results from the project were published in July in the journal Crops. The study, authored by a team of experts from CIMMYT, ICARDA, FAO, and research institutes in Afghanistan, Turkey and other countries in the region, compared the diversity, performance, and adaptation of the collected wheat landraces with modern varieties grown in the regions using a series of field experiments and cutting-edge genomic tools.
“Landraces are very useful from a breeding perspective because they have been cultivated by farmers over thousands of years and are well adapted to climate change, have strong resistance to abiotic stresses and have very good nutritional quality,” said Rajiv Sharma, a CIMMYT senior scientist and co-author of the paper.
“We were interested in seeing how well landraces adapt to certain environments, how they perform agronomically, and whether they are more diverse than modern varieties grown in these regions – as well as give their improved versions back to farmers before they are lost.”
The experiments, which were carried out in 2018 and 2019 in Turkey, and 2019 in Afghanistan, and other countries in the region revealed several physical characteristics in landraces which are no longer present in modern varieties. For example, the team found striking differences in spike and grain colors with landraces more likely to have red spikes and white grains, and modern varieties tending to have white spikes and red grains. This may have adaptive values for high altitudes and dry conditions.
A surprising finding from the study, however, was that landraces were not more genetically diverse than modern landraces.
“Many people thought that when we went from cultivating landraces to modern varieties, we lost a lot of diversity but genetically speaking, that’s not true. When you look at the genomic profile, modern varieties are just as diverse as landraces, maybe even a little bit more so,” said Sharma.
When the team compared landraces and modern varieties on crop performance, the results were mixed with modern wheat varieties outyielding landraces in half of the environments tested. However, they found that the highest yielding landraces were just as good as the best modern varieties – a reassuring finding for farmers concerned about the productivity of their crops.
A new breeding paradigm
The results of the study have important implications for landrace conservation efforts in farmers’ fields and in future breeding strategies. While crossing wheat landraces with modern varieties to develop improved modern varieties is not new, the authors proposed a novel alternative breeding strategy to encourage the continued cultivation of landraces: improving landraces by crossing them with other landraces.
“In order to maintain landraces, we have to make them competitive and satisfy farmers’ needs and requirements. One option is that we breed landraces,” said Sharma.
“For example, you might have a landrace that is very-high yielding but susceptible to disease. By crossing this variety with another landrace with disease-resistant traits you can develop a new landrace better suited to the farmer and the environment. This approach maintains all the features of landraces – we are simply accelerating the evolution process for farmers to replace the very fast disappearance of these traditional varieties.”
This approach has already been used by crop scientists at the University of California, Davis who has successfully developed and registered “heirloom-like varieties” of dry beans. The varieties trace about 98% of their ancestry to landraces but are resistant to the common mosaic virus.
Heirloom food products are becoming increasingly popular with health-conscious consumers who are willing to pay a higher price for the products, garnering even more interest in conserving traditional landraces.
One of the overarching aims of the project was to give wheat landraces back to farmers and let nature take its course. Throughout the mission, the team multiplied and returned landrace seed to over 1500 farmers in communities across Afghanistan, Turkey and other countries in the region. The team also supplied over 500 farmers with improved landrace seed between 2018 and 2019.
Despite the political turmoil facing these countries, particularly Afghanistan, farmers are still growing wheat and the project’s contribution to food security will continue.
These landraces will take their place once more in the farming landscape, ensuring on-farm wheat diversity and food security for future generations.
This research was conducted with the financial assistance of the European Union within the framework of the Benefit-Sharing Fund project “W2B-PR-41-TURKEY” of the FAO’s International Treaty on Plant Genetic Resources for Food and Agriculture.
